What is Evidence Based Nutrition
This matters to your health
The issue with untested drugs, herbs and homoeopathic mixtures, is not whether they work, it's more that they haven't been tested if they harm you either.
Information is powerful, more so when it is based on hundreds of carefully designed, unbiased, peer-reviewed trials. Personal opinion and anecdotes should fall short in influencing opinion, they are usually biased and uninformed.
A systematic review and meta-analysis, for instance, may contain data from 100,000 randomly assigned participants, this is far more powerful than a personal opinion based on 1 or 2 examples, even if they are a 'nutritionist'.
An opinion should be based on facts, with moral accountability, rather than: Fake news, Pseudoscience and self-proclaimed experts. Don't waste time, money and hopes on stuff that has not been proven not to do anything and might harm you.
